First Claim
1. An apparatus for displaying an operation sequence of a machine tool which is controlled by a numerical controller in accordance with a numerical control program, said apparatus comprising:
- operation memory means for memorizing data indicating successive operations;
numerical command memory means for memorizing data indicating successive numerical commands;
first memory control means for storing into said operation memory means data indicating successive operations instructed by an operator through command switches;
second memory control means for storing into said numerical command memory means data indicating successive numerical commands, which are commanded by a manual operation or by the numerical control program during the successive operations;
stopping means for stopping the operations of said first memory control means and said second memory control means when a malfunction occurs, anddisplay control means for displaying on a display device information indicating the successive operations together with the executed successive numerical commands based upon the data stored in said operation memory means and said numerical command memory means.

Abstract
An apparatus for displaying an operation sequence of a machine tool such as a grinding machine which is controlled by a numerical controller. During operation, successive operations instructed by a machine operator are stored in the memory of the numerical controller along with successive numerical commands which are executed during the successive operations. When a malfunction occurs in the machine tool, the storing operation is stopped, and the successive operations and the successive numerical commands executed before the occurrence of the malfunction are displayed on a display device for analyzing the cause of the malfunction.
